- Its nine MCP tools include multi-file signing, company stamps, and cleanup for signature files returned to the agent.
Field notes
Connection instructions show both command-line setup and a general MCP configuration block, with examples for Claude Code, Codex CLI, Claude Desktop, Cursor, Windsurf, and Gemini CLI. The listed tools also cover company text and stamp changes, which the page says require user confirmation. It says signature files delivered to an agent are deleted after ten minutes; its local-only and no-data-collection statements are claims made by the site.
